I've never tried that method, so I'm not sure of it.

What I do is take two fabrics and sew them together on one side (as if doing the strip tube)
Then take my strip tube ruler and make HST by placing the ruler on the line of the size I need for my HST.
It works like a charm and now I don't hate HST!

I go here: http://incompetech.com/graphpaper/ pick the size of shape with seam allowance then print out the size I need of any grid shape on freezer paper. Iron the fabric on the paper and cut. The software program is very good if you prefer a program. I have several Quilt Pro programs and they are all very nice.

there are free printables on line for making HST's.

you can get a HST up to 2.5 inches for free. Maybe print a couple pages make some to see if you like the paper method before spending the money on it.

here is a few: had to look them up

if you need more, i have them..

I have used Triangles on a Roll and love them. Also have a computer program for the pattern for numerous sizes.

I use the incompetech.com all the time for my PP shapes.
Sometimes you have to tweak your printer (enlarge/reduce button) aftrerwards to get the right size. I always mark the amount of increase/decrease % I did on the samples so I don't
get confused. Works like a charm. Also figured out how to print more patterns out on the same page once I get the size I want.
